6 Precision Casting Processes Under One Roof

Match your component mechanical stress, wall thickness, annual volume, and surface treatment requirements with the ideal metallurgical process.

HPDC±0.03

High Pressure Die Casting (HPDC)

High Pressure Die Casting forces molten aluminium or zinc under immense pressure (300 to 1,200 bar) into reusable hardened tool steel dies at speeds up to 60 m/s. It delivers near-net-shape geometry, exceptionally smooth surface finishes, and rapid cycle times.

Wall Range:1.2 mm – 8.0 mm
Locking Force:120T – 2,500 Tonnes
Cycle Speed:25 – 80 shots/hr
LPDC±0.10

Low Pressure Die Casting (LPDC)

In Low Pressure Die Casting, molten metal is housed in an airtight furnace beneath the die. Dry air or inert gas at 0.2 to 1.5 bar smoothly pushes the melt up a ceramic riser tube into the cavity from the bottom, completely eliminating turbulent oxidation and gas entrapment.

Wall Range:3.0 mm – 30.0 mm
Locking Force:Automated 4-column hydraulic rigs
Cycle Speed:8 – 18 shots/hr
Gravity Die Casting±0.20

Gravity Die Casting / Permanent Mould Casting

Gravity Die Casting relies solely on gravity to introduce molten metal into tiltable or static iron/steel permanent dies. Combined with sand cores, it produces intricate internal passages and deep hollow cavities impossible in HPDC.

Wall Range:3.5 mm – 45.0 mm
Locking Force:Mechanical and Hydraulic Tilt Units (up to 1,500 mm platen)
Cycle Speed:5 – 15 shots/hr
Hot & Cold Chamber±0.02

Hot Chamber & Cold Chamber Die Casting

Selecting between Hot Chamber and Cold Chamber depends fundamentally on the melting temperature and chemical reactivity of the casting alloy. We operate both specialized lines to provide the lowest cost-per-part.

Wall Range:0.6 mm (Zinc) | 1.5 mm (Aluminium)
Locking Force:Zinc Hot Chamber: 30T – 250T | Al Cold Chamber: 120T – 2500T
Cycle Speed:Hot: 150 – 500 shots/hr | Cold: 30 – 90 shots/hr
Vacuum HPDC±0.03

Vacuum Die Casting

Vacuum Die Casting integrates high-capacity evacuation valves that draw sub-30 mbar vacuum across the entire die cavity and shot sleeve in milliseconds just before injection. This removes 95%+ of trapped air, completely eliminating blister porosity and enabling weldability and T6 heat treatment.

Wall Range:1.5 mm – 10.0 mm
Locking Force:400T – 2,500 Tonnes
Cycle Speed:30 – 65 shots/hr
Squeeze Casting±0.05

Squeeze Casting

Squeeze casting combines the near-net-shape geometry of die casting with the metallurgical integrity of closed-die forging. Molten metal solidifies under massive, direct hydrostatic pressure (50 to 150 MPa) applied throughout the solidification window.

Wall Range:4.0 mm – 50.0 mm
Locking Force:350T – 1,800 Tonnes (Direct Squeeze Press)
Cycle Speed:12 – 25 shots/hr
